GM RWD mid-size and large Vans/SUV's (Jimmy, Bravada, TrailBlazer, Yukon, etc..) with an electronic 4sp automatic use the 4L60. The 4L60 has a known weakness with the Sun Gear Shell. It will take out 2nd, 4th and Reverse. This has been a known problem for years. It is not uncommom for the Sun Gear shell to crack at 70-80,000 miles. GM historically has not addressed this issue so if you use a GM part in the rebuild you may end up with the same issue. Do a Google search on "sun gear shell" and "4L60" and you'll see what I mean. If replacing the part use an aftermarket part that has addressed this issue. If you have this fixed at the GM dealer they will charge you $800, will only replace the Sun Gear shell, and it will happen again. If you must have a dealer do it beg them it use an alternative part.

For those you have a stock sun gear shell in your 4L60 simply don't floor it from a dead stop and avoid full throttle 4-2 downshifts. I have 215,000 miles on the 4L60 in my '96 Astro Van and after learning of this issue several years ago I simply take it easy. The 4L60 in general is a good trans and is an electronic version of the 700-4R used in the mid 80's up thru 1993. Since they were also used in the Vette's and Camaro's the aftermarket has many parts to significantly beef-up these transmissions in high horsepower applications.

I had a problem on my 99. It wouldn't engage in reverse. Turns out there was a Gear Hub that fractured. I had to have it rebuilt.

How do you fix rough idle on 88 astro van?

You should first look at your distributor closely because astros are known for having pick up coil problems. next is cylinder pressures. Cylinder pressure is probably the last thing to look at. If you are just having a rough idle you need to start with new spark plugs and wires. Clean out the throttle body. If there is no improvement from that then check for vacuum leaks and proper EGR flow. 4.3 Chevy engines are known for egr issues. Is the check engine light on? could even be an oxygen sensor problem.

4.3 liter Chevy chugs at 55 mph?

Could be a fuel issue. That motor has a "spider" type of injection in the intake, and is commonly known for failure. Or, the pump could be the culprit. Again, commonly known for problems. The EGR valve, has also been known to create symptoms such as thse, as well. All three are common to the 4.3.
